摘要： An automotive light comprising a lighting assembly which is located inside the rear body, is adapted to backlight a corresponding transparent or semi-transparent sector of the front half-shell, and comprises: a pair of light-guide bars made of photoconductive material, which extend toward each other inside the rear body, while remaining both substantially grazing the front half-shell, and have their respective proximal ends adjacent and aligned to one another; and a pair of electrically-powered light sources that are located within the rear body each adjacent to the distal end of a respective light-guide bar, and are oriented so as to direct the light produced inside the body of the facing light-guide bar; the proximal ends of both light-guide bars being shaped so as to form respective plate-like heads that are locally substantially coplanar to each other and are arranged inside the rear body one spaced beside the other, so as to form/delimit therebetween a small transversal slot, which is substantially straight and is inclined with respect to the local longitudinal axis of the same light-guide bars.

摘要： A lighting and/or signaling device, in particular for the automotive industry, comprising a container body which delimits a containment housing closed by a lenticular body, which accommodates at least one light source adapted to emit a light beam which at least partially crosses the lenticular body, at least one decorative element, applied on an external wall of the lenticular body, opposite to the containment housing. An internal wall of the decorative element, directly facing the external wall of the lenticular body, comprises at least one welding pin, which creates a welding point with the lenticular body. At least one spacer element defines a minimum clearance and a volume or gap between the external wall of the lenticular body and the internal wall of the element decorative element. At least one conveyor element favors the outflow of liquids which have penetrated through the clearance into the volume.

摘要： A lighting and/or signaling device comprising a container body which delimits a containment seat that houses a first luminous source adapted to emit a first luminous beam, and a second luminous source adapted to emit a second luminous beam. The containment seat adapted to be at least partially crossed by the luminous beams produced by said luminous sources, so as to transmit the luminous beams outside the containment seat. The containment seat is divided into a first compartment which houses the first luminous source and into a second compartment which houses the second luminous source. The lenticular body comprises a first transmission portion, facing the first compartment that transmits, at least partially, towards the outside the first luminous beam, a second transmission portion facing the second compartment that transmits, at least partially, towards the outside the second luminous beam. An opaque portion, is interposed between the first and second transmission portions so as to conceal the view of the first and second luminous sources.

摘要： An automotive lighting apparatus is provided that includes a rear body which is adapted to be fixed to the outside or to the inside of the vehicle; a front half-shell arranged to close the mouth of said rear body; and at least one lighting assembly which is located inside the rear body and is adapted to backlight, on command, a corresponding transparent or semi-transparent sector of the front half-shell; the lighting assembly including a radially emitting optical fibre of given length; an electrically-powered, collimated light source which is located in front of a proximal end of the optical fibre, and is adapted to direct, towards the same proximal end, a collimated light beam that enters and travels inside the optical fibre; at least one proximal photometric sensor which is arranged beside the collimated light source and/or the proximal end of the optical fibre so as to capture/detect the light reflected/scattered on entering into the optical fibre; at least one distal photometric sensor which is located in front of the distal end of the optical fibre, and is adapted to capture/detect the light exiting from the distal end of the optical fibre; and an electronic control unit which is adapted to command the collimated light source on the basis of the signals coming from said proximal and distal photometric sensors.

摘要： A lighting device including at least two LED light sources configured for individual activation; at least two light guides arranged adjacent to one another, each including an edge surface facing a respective one of the LED light sources, a back surface extending from the edge surface provided with a plurality of diffuser extractor elements, and a front surface extending from the edge surface and opposite the back surface; and opaque barrier walls provided between the at least two light guides and extending from the rear wall to the front wall, to mechanically and optically separate the light guides. The light guides are configured to receive light from the LED light sources, with the diffuser extractor elements arranged shaped redirect received light traveling within the light guide to be projected through the front surface.

摘要： Vehicle light comprising a container body, a lenticular body, a light guide, including a body having a prevailing longitudinal extension (L) that defines the propagation direction of the light beam inside the body by total internal reflection. The body has a first breakline that extends from the first to the second side wall. The first breakline includes a plurality of first holes that produce, through successive refractions, a scattering the light rays (Ri) towards the light outlet wall so as to emit a light beam with opalescent effect. The first holes are adjacent to each other without interruption, and the first holes of the first breakline are pass-through with respect to a thickness of the body of the light guide, penetrating from a first face to a second face of the body for a depth equal to the thickness.
